Rapid estimation of 4DCT motion-artifact severity based on 1D breathing-surrogate periodicity

PURPOSE: Motion artifacts are common in patient four-dimensional computed tomography (4DCT) images, leading to an ill-defined tumor volume with large variations for radiotherapy treatment and a poor foundation with low imaging fidelity for studying respiratory motion. The authors developed a method...
